SPECIFICATION lforming part of Letters Patent No. 744,06 5,'dated November 17, 1903.

' Application filed October 10, 1902. Serial No. 126,'7-02. (No model.)

To all whom, it rita/y concern: Y

Be it known that I, ALBERT GRAN, a citizen of the United States, and a resident of Ohicago, in the county of Cook and State of Illi nois, have invented a new and Improved.

Wind-Motor, of which the following is a full, clear, and exact description.

The invention relates to wind-motors such as shown and described in the Letters Patent of the United States No. 705,922, granted to me July 29, 1902.

The object of the present invention is to provide a new and improved wind-motor arranged to permit automatic adjustment of the chute directing the wind to the windwheel to insure uniform running of the m04V tor both in a heavy and light breeze. Y

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l isa longitudinal sectional elevation of the improvement on the line 1 l of Fig. 2. Fig. 2 is a front elevation of the same. Fig. 3 is an enlarged'sectional side elevation of the governor, the section being on the line 3 3 of Fig. at. Fig. 4 is a transverse section' of the same on the line 4 4 of Fig. 3, and Fig. 5 is a reduced side elevation of the improvement.

The tower or like support A is provided on its top with spaced bearings B and B', in which is mounted to turn thehub C of a frame C, provided in its sides with bearings for a shaft D, carrying a windfwheel E, preferably provided with curved buckets, as plainly illustrated in Fig. l. On the shaft D is secured a bevel gear-wheel F in mesh with a bevel 'as plainly indicated in Fig. l.

0n the frame C for the wind-Wheel is secured a vane H for holding the front of the wind-wheel E at all times to the wind, the latter being directed to the open ends of the buckets at the front of the wheel and near the top thereof by a chute I, having side walls -I secured to theframe C, and a bottom l2,

which extends upward and inward at the front of the wheel E to the peripheral surface of the said wheel, at about the middle thereof, This bottom I2 is supported from the sides l and serves to direct the wind into the lbuckets of the wind -wheel E at the upper front portion thereof. The chute I is further provided with va top 13, extending between' the sides I and fulcrumed at I4 on kthe frame C, directly above the center of the wind-wheel, and on the free end of the said top 13 is pivoted a downwardly-extending rack J inmesh with a pinion J', secured on a shaft J2, journaled in suitable bearings carried by the framework of the chute I, and on the outer end of the said shaft .l2 is secured a sprocket-wheel K, connected by a sprocket chain K with a sprocket-wheel K2, formed or secured ona governor-Wheel L, mounted to rotate loosely on the wind-wheel shaft D. (See Figs. 2, 3, and 4C.)

The inside of the rim of the governor-wheel L is adapted to be engaged by a lever N, fulcrumed at N on the inside of a disk O, se-

cured on the wind-wheel shaft D and serving to close the open end of the governor-wheel L. Thelever N is provided with va weighted arm N2 and is connected with a spring N5, attached to a bolt N4, held ad'justably on a disk O to allow of regulating the tension of the spring N3. Now when the wind-wheel E is rotated by the wind passing through the chute I onto the buckets of the wind-wheel E then the disk O rotates with the shaft D, and when the speed of the wind-wheel increases beyond a normal rate of speed then the weighted arm N2 of the lever N causes the latter to swing by centrifugal force into engagement with the governor-wheel L to rotate the latter with the diskO, shaft D, and wind-wheel E, and the rotary motion thus given to the governorwheel L is transmitted by the sprocket-wheels K2 K and sprocket-chain K to the shaft J2, which by the pinion J causes. the rack .l to

IOO

move downward, so that the top I3 is swung downward to reduce the size of the opening or entrance of the chute I, and thereby cut o some of the wind from the wind-wheel E to reduce the latters speed. When the speed ofthe wind-wheel falls below a normal rate, then the tension of the spring N3 causes a return swinging movement of the lever N to disconnect the disk O from the governor-wheel L to allow of opening the top I3 to admit more wind by the chute I to the wind-wheel E. In order to hold the top I3 normally in a full open position and to return the top to this open position after the governor is out of action, I provide the following device: The free end of the rack J is connected with one end of a rope, cord, or chain P, extending upwardly over a pulley P', journaled in the framework of the chute I, the rope then eX- tending inwardly over a pulley P2, journaled on the hub C' and guiding the rope to the inside of the huh for the rope to then extend downwardly to support a weight P3, mounted to slide on vertical guideways P", hung on a cross-bar P3, secured to the lower end of the hub C', as plainly shown in Figs. l and 5. The weight P3 has a tendency to push the rack J upward to hold the top I3 in an uppermost open position; but when the speed of the windmill increases beyond a normal rate then the governor, acting on and turning the pinion J', causes the latter to move the rack J downward to move the top I3 downward, and thereby reduce the entrance of the chute I to admit less wind to the wind-wheel. It is understood that when the rack J moves downward, as described, the weight P3 is drawn upward on its guideways P4, and when the speed of the windmill diminishes back to a normal rate then the weight overcomes the centrifugal action of the governor and causes a return or upward movement of the rack J and top I3 to open the chute I toits full capacity.

Mounted to slide on the guideways PtL is a sleeve Q3, connected by a rope or chain Q5 to the staple P6 on the weight P3, and loosely mounted on the said sleeve is a ring Q4, with which the hook Q on one end of the rope Q is adaptedto be engaged, said rope passing over a pulley Q3, journaled in the upper portion of the tower A, as plainly shown in Fig. 5. The downward-hanging end of the rope Q is under the control of the operator standing on the ground, so that when the hook Q is engaged with the ring QL and the operator pulls on the downward hanging end of the rope then the Weight ID3-slides upward on its guideways, and thus relieves the rack-bar J and top I3 of its; pressure to allow the top I3 to completely close the entrance of the chute, and thereby stop the windmill.

It is understood that the shaft G extends loosely through an opening in the middle of the counterbalancing-weight P3 for the top I3v of the chute, so that the shaft can rotate independently of the said weight, which has a free up-and-down movement on its guideways P4, and the latter and the weight turn with the hub C and frame C, controlled in its turning motion by the vane H, it being expressly understood thatthe vane H holds the chute I and wind-wheel E always to the wind to utilize the force of the wind to the fullest advantage. When the top I3 is in a normal open position, as shown in Fig. 1, then the inner end of the chute next to the wind-wheel E is somewhat contracted to cause compression of the wind and immediate expansion thereof as soon ,as it reaches the buckets of the wind-wheel E.

Having thus described my invention, I lclaim as new and desire to secure by Letters Patent- 1.
